Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary tools for cutting castings, and in particular to an auxiliary tool for cutting castings. Background Technology

[0002] When a saw is cutting a casting with a hollow structure that is high on the outside and low on the inside, the cutting fluid tends to flow into the casting and accumulate in large quantities as the saw blade moves. This not only increases the burden of manually cleaning the cutting fluid, but also causes the saw blade to wear faster due to insufficient lubrication and cooling caused by insufficient circulation of the cutting fluid.

[0003] To prevent cutting fluid from seeping into the casting, a common practice is to place plastic-wrapped sandbags as a barrier near the inner end of the casting. During cutting, the sandbags effectively prevent the cutting fluid from flowing into the casting, ensuring that the cutting fluid is isolated outside the casting.

[0004] However, using sandbags as a cutting fluid blocking measure has limitations. Sandbags mainly rely on their own weight to adhere to the casting. When the casting structure is complex, the adhesion is poor, which may cause cutting fluid to seep into the casting, increasing the burden of manual cleaning. In addition, the slight vibration of the casting during cutting can easily cause the sandbag to shift or fall off, which can also cause cutting fluid leakage, affecting the circulation of cutting fluid on the saw and thus accelerating the wear of the saw blade. Utility Model Content

[0006] Therefore, one objective of this utility model is to provide an auxiliary tool for cutting castings. By using a limiting rod, the flexible layer can be tightly fitted to the casting to prevent it from shifting or falling off, thereby effectively preventing cutting fluid from entering the interior of the casting. At the same time, its installation and disassembly process is simple and quick.

[0007] To achieve the above objectives, the first aspect of this utility model provides an auxiliary tool for cutting castings, comprising a flexible layer, a support portion, and a limiting rod, wherein the flexible layer covers the lower surface of the support portion, the support portion is provided with a connecting block, and the limiting rod is threadedly connected to the connecting block.

[0008] This utility model provides an auxiliary tool for cutting castings. By using a limiting rod, the flexible layer can be tightly fitted to the casting to prevent it from shifting or falling off, thereby effectively preventing cutting fluid from entering the interior of the casting. At the same time, its installation and disassembly process is simple and quick.

[0019] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention. Rather, the embodiments of the present invention include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0020] The auxiliary tool for cutting castings according to an embodiment of the present invention will now be described with reference to the accompanying drawings.

[0021] like Figures 1 to 3 As shown, the auxiliary tool for cutting castings according to this utility model embodiment may include a flexible layer 11, a support part 12 and a limiting rod 13, wherein the flexible layer 11 covers the lower surface of the support part 12, the support part 12 is provided with a connecting block 14, and the limiting rod 13 is threadedly connected to the connecting block 14.

[0022] It should be noted that the shape of the support portion 12 described in this embodiment is not limited and can be square, elliptical, etc. The specific shape can be set according to the internal shape of the casting, so that it can be applied to different castings.

[0023] Furthermore, the limiting rod 13 is provided with an external thread, and the connecting block 14 is provided with an internal thread. The external thread and the internal thread cooperate with each other to realize the threaded connection between the limiting rod 13 and the connecting block 14.

[0024] In one embodiment of this utility model, such as Figure 1 As shown, the flexible layer 11 is made of rubber, and the shape of the flexible layer 11 fits the blocking position 4.

[0025] In the embodiments of this utility model, the rubber material is soft, does not react with cutting, and does not absorb water, so it can fit tightly with the blocking position 4 and has a good blocking effect on the cutting fluid.

[0026] In one embodiment of this utility model, such as Figure 1 As shown, the top of the limiting rod 13 is spherical or conical.

[0027] In the embodiments of this utility model, the top of the limiting rod 13 is set in a spherical or conical shape, which can adapt to the narrow space inside the casting, thereby facilitating the fixation of the support part 12 by using the limiting rod 13.

[0028] In one embodiment of this utility model, such as Figure 3 As shown, the height of the support part 12 is greater than the maximum height of the blocking position 4, that is, the support part 12 is higher than the highest point of the blocking position 4, so as to facilitate the flow of the blocked cutting fluid out of the casting.

[0029] Specifically, refer to Figure 2 and Figure 3 When installing the tool of this utility model, first place the entire tool inside the casting 2 and make the flexible layer 11 fit with the blocking position 4. Then rotate the limiting rod 13 and move the limiting rod 13 upward. Finally, the top of the limiting rod 13 is pressed against the inner upper wall of the casting. At this time, the flexible layer 11 outside the support part 12 fits tightly with the blocking position 4 and will not shake. Finally, the cutting position 3 can be cut by the saw blade to cut the casting 2 into the outer side 21 and the inner side 22 of the casting.

[0030] In summary, the auxiliary tool for cutting castings according to this utility model embodiment can make the flexible layer fit tightly with the casting through the limiting rod, preventing it from shifting or falling off, thereby effectively preventing cutting fluid from entering the interior of the casting. At the same time, its installation and disassembly process is simple and quick.
